Yeah, I remember a while back I was adding Castrol Fuel Doctor to my diesel tank and the bloke next to me asked if it did any good. I said blowed if I know mate, but it makes ME feel good!

Yeah, Just after this incident I went to the local diesel service and asked one of their mechanics. His response was definitely use it especially in diesels and when you are travelling using lots of different and possibly less reliable suppliers.

I use Chemtech Diesel stuff every fill-up in my Silverado's Duramax.

The way I see it, I paid $105- for 5 litres of the stuff and use 100ml per 100 litres everytime I fill up. I use around 16 litres (of diesel) per 100 kilometers, so 100 litres of diesel (and 100ml of Chemtech) will get me around 625 kilometers.

Therefore, my 5 litre drum of Chemtech should last me for 31,000 kilometers......and cost me about 33 cents per 100 kilometers.

Compare that to the potential cost of 8 new injectors for this truck and all of a sudden the initial outlay of $105- sounds pretty cheap to me!!

People take vitamins and supplements and who knows if the do much good. We take out insurance for events that we do not expect to happen. We put second fuel filters on just in case we get bad fuel. We put winches on just in case we get stuck and there is no one else around and there are plenty of trees Roachie's use of Chemtec is in the same vain and very hard to fault his logic.
What other people think of me is none of my business.

Hiya Idler Chris but being a mechanical device surely there's some evidence it works bit different to ingesting vitamins ..

Roachie, if I am not wrong I think you will find that your Silverado additive had nothing to do with cleaning injectors and more to do with meeting emission requirements.

Sorry John....can't agree with you there. I think perhaps you are getting diesel additive with "Adblue"?

I do the same as Roachie - use Chemtech every tank. Been doing this for over 25 years.

On my old 47, 61 and 79 series diesels it would reduce smoke out the exhaust and improve fuel consumption.

On the 200series and our Tiguan, it is used because it has an algaecide and because it precipitates emulsified water. And those vehicle run sweet when I use it.
It only adds about 3c per litre to the cost. I've not had an injector issue on any vehicle, and never had water or algae in my fuel and I'm the one who has done every fuel filter replacement in that time.

I first started using it when recommended by a truckie.

I've also fitted a FASS 150 lift pump/water trap/filter close to my tank on the Silverado.

Looking at the youtube blurb, I was convinced about the level of injector damage that can be caused by air in the fuel as well as the idea that it takes away some of the effort required by the CP4 injector pump to suck the fuel 3+ meters from the tank to the engine.

Maybe it's snake oil, but I've fitted it and have no regrets.

hi
commercial injector cleaner works 100% used during cleaning, testing etc etc
Domestic cleaner 50/50
Domestic cleaners donot clean 100% nor will they stop water or algae growth, in a tank 100% either.This includes carbon build up also .
Better than nothing but not bullet proof or 100 honest .
If your engine develops an issue the cleaner will have zero benefit .
Injectors on petrols can still block up if a misfire occurs . Domestic cleaner will not fix this .
The cleaner would typically have greatest benefit to emission readings .

HI
Domestic cleaner is what u find at supercheap etc . Commercial cleaners are used when cleaning injectors off car mainly .Connect injectors to injector machine which would buz the injector at different rates when it is bathing in the fluid [ultrasonic cleaner ],there is an on car machine also [carbon clean ]. Mainly for petrol vehicles .Both systems have there pros and cons .
We used to sub out the diesel injector/pump stuff .The later DID injectors would also be using an injector cleaner . Apparently treated the same way petrol injectors are ,although I cannot confirm this. They are now reconditioning DID injectors.

Good sense of humour.Looks like most 4wheel drives these days are on steroids! Apparently tye LC.is getting bigger on the outside but smaller inside.Even from 60series to 80series I noticed less space inside...

Premium fuels have cleaner in them. That may do something.

I used to put petrol injector additive in the sedan. On the other hand, I have mates with over 100,000 kms on their sportsbikes, which have highly tuned engines, that never saw a drop without ill effect.

I'd never used the stuff but when Supercheap had their own brand injector cleaner on sale for $2 instead of the usual $12 or $13 I decided to give it a try in my 4.2 Nissan diesel. I put it into both tanks, from which I have been getting a range of around 1000kms. With the injector cleaner in I could feel absolutely no difference to performance, but by the time I needed to refill I had covered 1140 kms of the same type of driving I usually do.

I put the significant improvement in the fuel consumption down to the fact that I had removed the rooftop tent! :)

Chemtec also make a great engine oil gallery cleaner , when we had the 80 series turbo diesel by the book oil and filter change was stated as 9lt , and the new oil would be black after 100 or so km . Used as directed the additive to the oil prior to the next oil change ,11lt of the blackest thick gunk came out of the drain hole , and oil stayed clean and bright from 1 change 5k to the next .
